Advice Plz... 😭💀

I called a girl toxic and now she's telling everyone I called her toxic for no
reason, and she was telling her friends she was gonna get her mom to get me
expelled. Her friend also was talking about how she was gonna jump me. 💀 I
not scared of them, but they are gossip queens. This girl once bullied a girl and
spreed a rumor about how a girl was lesbian when the girl was straight.
